"This...how did such a disgusting thing appear in the laboratory?" Meng Yao's face turned a little pale. She almost put her finger on it just now, but fortunately it was quickly taken back.

Similarly, Chen Qingzhi was also glad that he reacted quickly. He didn't touch the corpse powder with his hands. Just thinking about it made him feel goosebumps all over his body.

"There is naturally a reason why the corpse powder appears here."

Qin Yu's fingers were stained with a trace of corpse powder, and the expression on his face remained unchanged, as if it was ordinary powder. He reached into his pocket with the other hand and took out a lighter. After igniting it, the flame moved to the powder of the finger.

With a "boom", a strange blue flame emerged from Qin Yu's fingers and had not yet been extinguished. After a while, Qin Yu's fingers swayed, and the blue flame was like an elf, dancing at Qin Yu's fingertips.

"Go."

Then, Qin Yu waved his fingers, and the dancing blue flames wandered around the entire laboratory like ghosts, making Meng Yao and Chen Qingzhi stunned.

"Did you feel that the temperature around you has dropped?" Qin Yu's voice slowly rang in the ears of the two women.

After Qin Yu's reminder, Meng Yao and Chen Qingzhi really realized that the temperature in the laboratory had dropped, and their skin had already had a hint of chill, but if it weren't for Qin Yu's reminder, the two women wouldn't have noticed it at all.

"Corpse powder burns will absorb a lot of heat from the surrounding space, causing the temperature to drop. Moreover, most people cannot detect it. Some people even have goose bumps all over their bodies because of the cold. However, this is not the most powerful place for corpse powder. The most powerful place for corpse powder is that it can make people hallucinate. Moreover, the master of corpse powder can control this illusion, that is, at this moment, if I am a master of corpse powder, I can control your senses and see whatever you want you to see." Qin Yu waved his hand, and the blue flame flew back to his fingertips again, beating there.

"Isn't that the same as hypnosis?" Meng Yao summarized.

"It's almost the same, but the hypnosis requires the cooperation of the person involved, and the corpse powder is completely silent." Qin Yu nodded and replied.

"But what do these people want to do with corpse fans?" Chen Qingzhi asked in confusion.

Qin Yu looked at Chen Qingyi's eyes and smiled and said, "Of course I want to control your mentor. I draw the news they want from your mentor, but unfortunately, they failed."

"How do you know they failed?" Chen Qingzhi asked.

"It's very simple. If you succeed, your mentor will not be taken away. Either those people get what they want and leave, or kill people to silence them, and then kill your mentor, but now the situation is that your mentor is taken away by them, which means that in the laboratory, these people don't get what they want, or message."

Qin Yu analyzed that Chen Qingzhi could not find any rebuttal. In the end, she had to admit that what Qin Yu said was correct.

"But what do they want to get from the tutor? No, the tutor is still in danger, so they must rescue the tutor." Chen Qingzhi's face became anxious again. "Mr. Qin, let's call the police. If these people take the tutor away, there will definitely be cars. If the police come to check the school's surveillance, they will definitely find theirs."

"No." Qin Yu shook his head, "It's not that I don't want you to call the police. The police can't handle this matter. If you believe me, just leave it to me. I will find a way to rescue your mentor, but I need your cooperation."

Chen Qingzhi stared at Qin Yu, and after a while, he finally compromised and nodded and agreed, "Okay, I can cooperate with you."

"First of all, you have to tell me what your supervisor is studying and his progress. The more detailed the better." Qin Yu's expression became serious and he asked Chen Qingzhi.

"This..." Chen Qingzhi looked embarrassed, "Actually, I don't know much. Most of the time I just helped the tutor. However, once I heard the tutor accidentally say that he cracked an ancient secret letter, and the content in this secret letter involved the secret of "becoming an immortal."

"Become an immortal?" A flash of light flashed in Qin Yu's eyes, he frowned, and he vaguely grabbed something in his mind.

"Does it feel ridiculous? When I first heard the mentor say it, I also felt it was absurd. How could there be immortals in this world? Even if there are, they are the gods of the past, but the mentor told me that people can become immortals."

"The tutor saw that I didn't believe it, but he didn't say much. He just told me that what he is studying now is related to becoming an immortal. Perhaps it is not the kind of "becoming an immortal" we understand. To be more precise, it is to have the same ability as the legendary gods, and can call the wind and rain, and overwhelm the sea."

Chen Qingzhi smiled bitterly on his face, as if he was falling into memories, "Even if the tutor said this, I still don't believe it in my heart, because how could a person have such great skills? This is completely subverting science. However, afterwards, the tutor began to take me to study the Zhouyi culture, and my views gradually changed."

According to Chen Qingzhi, after studying Zhou Yi, her entire worldview has undergone major changes. Some things that she thought were simply illusory and unscientific actually existed. After the mentor showed some of the skills of Zhou Yi, Chen Qingzhi finally believed that there is indeed a kind of person in this world who can do things that ordinary people cannot do with some special means.

"After that, I started to study with the tutor. However, the tutor often went back to disappear alone for ten days and half a month. Every time it appeared again, it was either a new discovery or a dejected person, and the tutor didn't tell me where I was going."

"What happened to Mr. Wolong, I said before?" Qin Yu frowned. Chen Qingzhi said this and felt that it was vain. There was no clue.

"When it comes to Zhuge Liang, it is because all this is caused by Zhuge Liang's secret letter. The secret of becoming an immortal was also discovered in Zhuge Liang's secret letter."

"Where is that secret letter now?" Qin Yu asked quickly.

"I don't know this. I haven't read the content of the secret letter. Only my mentor has read it. I just listened to his oral statements." Chen Qingzhi shook his head and said.

"If that's the case..." Qin Yu pondered for a while and said, "I'll make a call first."

Walking aside, Qin Yu dialed a number, and after the phone was called, he spoke, "Director Qiu, happy new year, haha, it's a good time, yes, there's something to bother you, I'm in Beijing now..."

"The news from Director Qiu is very well-informed. He knows that he is about to get engaged. The intelligence work of these special departments is really terrifying." After hanging up the phone, Qin Yu muttered.

Ordinary police officers will definitely not be able to deal with this matter. Qin Yu can be sure that the person who attacked Chen Qingzhi was definitely a person in the metaphysical world, and he could only be handled by people from special departments like Qiu Yun.

"Miss Chen, have you ever seen this key?" Qin Yu took out the key from the safe he picked up from under the peach tree from his pocket and asked Chen Qingzhi.

"Isn't this the key on the tutor? Yes, it's on the tutor, and the tutor never leaves the body. I remember one time the tutor was temporarily pulled to attend a meeting by the school leader. After changing a set of clothes, he hurried back when the meeting was halfway through, just to come back to get the key. For this reason, he was criticized by the school leaders and even the experimental funds were deducted." Chen Qingzhi took the key from Qin Yu's hand and looked at it for a while, and answered affirmatively.

After hearing Chen Qingzhi's words, Qin Yu and Meng Yao looked at each other, and thoughtful expressions appeared in their eyes. According to Chen Qingzhi, her tutor was very concerned about this key, and even threw away the research funds and offended the school leaders. How could he throw this key under the peach tree?

"Unless he did it on purpose." Meng Yao suddenly spoke, but Chen Qingzhi heard it for no reason, "What did it on purpose?"

"I picked up this key under the peach tree downstairs. I guess it fell from the second floor. Since you said your tutor is very precious to this key, it is generally impossible for this key to fall under the peach tree unless your tutor intentionally does this, or the situation at that time forces him to do it."

A glimmer flashed in Qin Yu's eyes, he took Meng Yao's words and explained to Chen Qingzhi. In Qin Yu's mind, there was even a complete speculation.

When Chen Qingzhi's mentor faced the mysterious group, it was obvious that he did not resist, or that it was useless to resist, so he chose to leave with the other party. However, Chen Qingzhi's mentor secretly threw the key from the second floor when the group was not paying attention.

"But why did Chen Qingzhi's mentor do this?"

Almost at the same time, Meng Yao and Chen Qingzhi spoke, "Did those people come for this key?"

"I think so too. To be precise, it comes for the things in the safe that the key can be opened. I guess Ms. Chen's mentor also knows the other party's purpose, so I threw the key away. It seems that we have to find it before the other party finds the safe. As long as the other party does not find the safe and does not get the things inside, Ms. Chen's mentor is safe." Qin Yu echoed.

"Then where will this safe be?" Meng Yao asked in confusion.

"Miss Chen, you have been with your mentor for so long. Have you ever seen a safe?" Qin Yu asked Chen Qingzhi.

"No, I have never seen a tutor open a safe with this key in school." Chen Qingzhi shook his head and replied. (To be continued, please search for Astronomy, novels are better, updated and faster!
